- the suction airflow supplied by the vacuum cleaner is often used for collecting debris and depositing the debris in a collector or compartment.
- These collectors are often removable from the power head to empty the collector
- the invention provides a modular vacuum system including a first canister with a first capacity configured to store debris, a second canister with a second capacity greater than the first capacity, a first power head and a second power head.
- the first power head is coupled to either the first canister or the second canister.
- the first power head is operable at a first voltage to generate a first suction airflow, and the first power head can be coupled to the first canister such that the first canister receives the first suction airflow.
- the first canister stores debris separated from the first suction airflow.
- the first power head can be coupled to the second canister such that the second canister receives the first suction airflow.
- the second canister stores debris separated from the first suction airflow.
- the second power head can be coupled to either the first canister or the second canister.
- the second power head is operable at a second voltage, greater than the first voltage, to generate a second suction airflow, and the second power head can be coupled to the first canister such that the first canister receives the second suction airflow.
- the first canister stores debris separated from the second suction airflow.
- the second power head can be coupled to the second canister such that the second canister receives the second suction airflow.
- the second canister stores debris separated from the second suction airflow.
- the invention provides a modular vacuum system including a first canister with a first capacity configured to store debris, a second canister with a second capacity greater than the first capacity, and a power head that can be coupled to either the first canister or the second canister.
- the power head is operable to generate a suction airflow.
- the power head can be coupled to the first canister such that the first canister receives the suction airflow and the first canister stores debris separated from the suction airflow.
- the power head can be coupled to the second canister having a greater capacity than the first canister such that the second canister receives the suction airflow and the second canister stores debris separated from the suction airflow.
- FIG. 1 is a perspective view of the modular vacuum system according to one embodiment of the invention.
- FIG. 2 is a perspective view of the modular vacuum system of FIG. 1 with a canister and a power head removed from a cart.
- FIG. 3 is a perspective view of the power head removed from the canister.
- FIG. 4 illustrates a variety of canisters with mating cross-sections corresponding to a mating cross-section of the power head.
- FIG. 5 illustrates a variety of canister paired with a variety of power heads.
- FIGS. 1-5 illustrate a modular vacuum system 10 .
- the modular vacuum system 10 includes a first power head 12 , a second power head 14 , a first canister 16 , a second canister 17 , a third canister 18 and a base 20 .
- the power heads 12 , 14 can be connected to canisters 16 , 17 , 18 by using a latch 19 , and the canisters 16 , 17 , 18 can be connected to the base 20 .
- the latch 19 can be actuated to lock or release the power heads 12 , 14 to the canisters 16 , 17 , 18 .
- the power heads 12 , 14 have different performance levels and the canisters 16 , 17 , 18 have different capacities. Therefore, the user can select the power head performance, the canister size, and the base 20 for a modular and custom design to fit the user's needs.
- FIG. 5 illustrates the first power head 12 and the second power head 14 .
- the first power head 12 has a first performance level and includes a first fan 21 and a first motor 22 .
- the second power head 14 has a second performance level generally exceeding the first performance level and includes a second fan 23 and a second motor 24 .
- the first performance level has a first voltage and the second performance level has a second voltage greater than the first voltage.
- the first voltage is provided by an 18 volt lithium-ion battery 25 .
- the second voltage is provided by two of the 18 volt lithium-ion batteries 25 that create a 36 volt system. In other embodiments, different battery voltages can be used.
- the power heads 12 , 14 include an AC power input 26 to charge the 18 volt lithium-ion battery 25 , and/or to power the power heads 12 , 14 when the 18 volt lithium-ion battery 25 is not used.
- the power heads 12 , 14 may be only powered by the AC power input 26 .
- the power heads 12 , 14 may include a horizontal filter.
- the filter is interchangeable for various purposes—wet, dust, HEPA, etc.
- the filter includes a visual indicator on the side of the filter so the user knows what type of filter wet, dust, HEPA, etc.) is installed.
- the canisters 16 , 17 , 18 have multiple canister sizes.
- the first canister 16 has a capacity ranging from two gallons to six gallons.
- the second canister 17 has a capacity ranging seven gallons to sixteen gallons.
- the canisters 16 , 17 , 18 may have capacities ranging from two gallons to twenty gallons.
- the canisters 16 , 17 , 18 have an open upper end 27 and a closed lower end 28 .
- FIG. 5 illustrates the first canister 16 with a first height 30 measured from the open upper end 27 to the closed lower end 28 .
- the second canister 17 has a second height 31 and the third canister 18 has a third height 32 .
- the shape of the open upper end 27 has a first polygonal cross-section 33 and the shape of the closed lower end 28 has a second polygonal cross-section 34 .
- the size and shape of the open upper end 27 and closed lower end 28 are consistent across the canisters 16 , 17 , 18 . Therefore, the capacity of each canister in the illustrated embodiments is varied by the heights 30 , 31 , 32 of the canisters 16 , 17 , 18 .
- the canisters 16 , 17 , 18 can connect with the power heads 12 , 14 at the open upper end 27 , and they can connect to the base 20 at the closed lower end 28 .
- the base 20 includes a handle 38 , a release 40 , a wheels 41 , and a brake 42 .
- the release 40 is used for unlocking the canisters 16 , 17 , 18 from the base 20 (e.g., for emptying or for changing the canister or the base).
- the handle 38 is an adjustable handle connected to the base 20 used to move the canisters 16 , 17 , 18 when they are attached to the base 20 .
- the release 40 is a release lever actuated to remove the canisters 16 , 17 , 18 from the base 20 .
- the release 40 may be foot actuated release lever.
- the brake 42 prevents the base 20 from moving by locking at least one of the wheels 41 .
- the canisters 16 , 17 , 18 can stand freely without the base 20 . That is, the canisters 16 , 17 , 18 can be set on the ground, and the modular vacuum system 10 can be used without the base 20 .
- the canisters 16 , 17 , 18 may include integrated handle(s) for emptying.
- the modular vacuum system 10 includes an inlet 44 attached to the first power head 12 .
- a hose 48 is removably coupled to the inlet 44 .
- the first motor 22 is operated at the first voltage to generate a first suction airflow through the inlet 44 .
- the first suction airflow collects debris that passes through the inlet 44 .
- the debris is separated from the first suction airflow and stored in the canisters 16 , 17 , 18 .
- the inlet 44 may be attached to the second power head 14 .
- the second motor 24 generates a second suction airflow through the inlet 44 , where the second suction airflow collects debris, and the debris is separated from the second suction airflow and deposited in the canisters 16 , 17 , 18 .
- FIG. 5 illustrates the modularity of the modular vacuum system 10 illustrates the canisters 16 , 17 , 18 coupled to the power heads 12 , 14 such that the canisters 16 , 17 , 18 may receive the first or second suction airflow generated by the power heads 12 , 14 .
